Based on Kabalah, some are accustomed to sit facing south during the Seder.[1] The Chabad custom is not to be particular as to which direction to face during the Seder, and hence one may sit in any direction one chooses, facing east, west, north or south.[2]

• Maaseh Rebbe:[3] By the Seder table of the Rebbe Rayatz in New York, the Rebbe Rayatz sat facing east, and the Rebbe sat to his left, facing south.
